Laptop connects to my home network, but not to the internet?

My Dell XPS laptop, running Windows Vista, will connect to my wireless network but will not get on the internet. My router is a WRT320N and I am using the laptops built in wireless card. The LEA program sees the laptop and shows it as connected. How do I fix that?

As you Vista Laptop is already connected to the Wireless Network. On your Vista Computer click on Start - Search - CMD and in the Command Prompt window type "Ipconfig" and hit enter and check whats the IPv4 IP address.

Disable the Firewall and Antivirus on your Computer and then check if you are Online.
